Waterbox Removal and Installation
Important: Only qualified technicians should perform
the installation and servicing of this
equipment.
Discussion
This section will discuss recommended lifting. Proper
lifting technique will vary based on mechanical room
layout.
• It is the responsibility of the person(s) performing the
work to be properly trained in the safe practice of
rigging, lifting, securing, and fastening of the
waterbox.
• It is the responsibility of the person(s) providing and
using the rigging and lifting devices to inspect these
devices to ensure they are free from defect and are
rated to meet or exceed the published weight of the
waterbox.
• Always use rigging and lifting devices in accordance
with the applicable instructions for such device.
Procedure
Review mechanical room limitations and determine the
safest method or methods of rigging and lifting the
waterboxes.
1. Determine the type and size of chiller being serviced.
Refer to Trane nameplate located on chiller control
panel.
Important: This literature contains rigging and lifting
information only for Trane CTV chillers built
in La Crosse. For Trane CTV chillers built
outside the United States, refer to literature
provided by the applicable manufacturing
location.
2. The rated lifting capacity of the lifting shackle must
meet or exceed the published weight of the waterbox.
Verify the waterbox weight from the latest published
literature.
3. Ensure that the lift connection device has the correct
size for the waterbox lifting hole.
4. Properly connect the shackle to the
waterbox.Figure 54, p. 98
5. Disconnect water pipes, if connected.
6. Remove waterbox bolts.
7. Lift the waterbox away from the shell.
8. Store waterbox in a safe and secure location and
position.
Note: Do not leave waterbox suspended from lifting
device.
WARNING
Heavy Objects!
Failure to properly lift waterbox could result in death or
serious injury. Each of the individual cables (chains or
slings) used to lift the waterbox must be capable of
supporting the entire weight of the waterbox. The
cables (chains or slings) must be rated for overhead
lifting applications with an acceptable working load
limit. Refer to
Table 24, p. 99 for waterbox weights.

WARNING
Overhead Hazard!
Failure to follow instructions could result in death or
serious injuries. Never stand below or in close
proximity to heavy objects while they are suspended
from, or being lifted by, a lifting device in case the
object drops.
